Golf swing measurement device and golf swing measurement system

Golf swing measurement device and golf swing measurement system description/claims

The present invention relates to a golf swing measurement device and a golf swing measurement system for measuring and calculating measurement data such as a swing time from a start moment of a backswing of a golf club to a moment of an impact on a golf ball, a head speed of the golf club upon the impact, and a total flying distance, so that the measurement data can be displayed. According to the present invention, the golf swing measurement device is capable of storing the measurement data and forwarding the measurement data thus stored to a personal computer and the likes. Accordingly, it is possible to use the measurement data for analyzing a golf swing at an arbitrary location, thereby assisting a golfer to improve skills.

Patent Reference discloses a conventional golf swing measurement device. The conventional golf swing measurement device measures a swing time from a start moment of backswing of a golf club to a moment of an impact on a golf ball (referred to as a swing time), and a head speed upon the impact (referred to as a head speed).

In the conventional golf swing measurement device, a first sensor coil and a second sensor coil are arranged to be substantially parallel to a swing path of a golf club head. Further, a permanent magnet is attached to a distal end portion of a golf club head. Accordingly, when the golf club is swung, the first sensor coil and the second sensor coil detect the club head passing therethrough, and a detection signal is sent. With the configuration described above, it is possible to calculate the swing time and the head speed according to the detection signal of the first sensor coil and the second sensor coil. Patent Reference: Japanese Patent Publication No. 11-290496

With the conventional golf swing measurement device disclosed in Patent Reference, a golfer measures the swing time and the head speed at a place such as a driving range where the golfer swings a golf club. Accordingly, it is possible to utilize measurement data on the spot of practice. However, it is difficult to analyze the golf swing using the measurement data at such a place as a home other than a driving range. Further, with the conventional golf swing measurement device, it is difficult to measure an index value associated with the golf swing other than the swing time and the head speed.

In view of the problems described above, an object of the present invention is to provide a golf swing measurement device capable of analyzing a golf swing using measurement data at such a place as a home other than a driving range, as well as measuring the swing time and the head speed at such a place as a driving range where a golfer swings a golf club.

Further, with the golf swing measurement device of the present invention, it is possible to calculate and display an index value associated with the golf swing in addition to the swing time and the head speed. Accordingly, it is possible to provide the golf swing measurement device capable of utilizing the measurement data of the golf swing more effectively, thereby improving skills in the golf swing.

Further objects and advantages of the invention will be apparent from the following description of the invention.

In order to attain the objects described above, according to the present invention, a golf swing measurement device has a box shape, and is placed in front of a golfer when the golfer swings a golf club to hit a golf ball. The golf swing measurement device includes:

a sidewall portion extending substantially in parallel to a swing path of the club head;

a first sensor coil disposed along the sidewall portion and a second sensor coil disposed along the sidewall portion at a front position of a swing path with respect to the first sensor coil by a specific distance for detecting a club head with a permanent magnet on a distal thereof passing therethrough;

a calculation unit for calculating a swing time from a start moment of a backswing to a moment of an impact, a head speed upon the impact, and a total flying distance according to a detection signal of the first sensor coil and the second sensor coil;

a display unit for displaying the swing time, the head speed, and the total flying distance;

a memory unit for storing measurement data including the swing time, head speed, and the total flying distance for a plurality of swings; and

a transmission unit for sending the measurement data stored in the memory unit to a personal computer when a specific operation is executed in the golf swing measurement device or an instruction is sent from the personal computer.

According to the present invention, the golf swing measurement device has the memory unit for storing the measurement data and the transmission unit for sending the measurement data stored in the memory unit to the personal computer. Accordingly, it is possible to analyze the golf swing using the measurement data at such a place as a home other than a driving range with software of the personal computer through sending the measurement data from the golf swing measurement device to the personal computer.

Further, with the golf swing measurement device of the present invention, it is possible to calculate the total flying distance (an estimated value of the total flying distance). Accordingly, it is possible to measure an index value relating to the golf swing other than the swing time and the head speed.

In the golf swing measurement device of the present invention, it is preferred that the display unit displays each of the head speed, the total flying distance, and the swing time for a specific period of time in this sequence. Then, the display unit displays the head speed and stops changing the display. Accordingly, it is possible for the golfer to confirm whether the swing is measured.
